Well you know Igor, I'm getting pretty old so I don't remember the problem you are describing except as some vague memory possibly. The problem I'm speaking of happens on all quad core machines as far as I know. At least, everyone I know with a quad core box. It has nothing to do with amd64 or not. The problem may also show up on dual core machines except that it happens with less frequency thus not being noticed as the same issue.
